I think it would be most likely A the first one.
Answer:
b is the answer
Step-by-step explanation:
i did some research
surface area = 4 x pi x r^2
diameter = 1 so radius = 1/2 = 0.5
4 x 3.14 x 0.5^2 = 3.14 meters^2
Subtract 6 from both sides, you get 1/3x=-14
Now multiply both sides by there, hence x=-42
